How to use resilience4j on calling method? - spring-boot

Question

I tried to use spring retry for Circuit breaking and retry as below and it is working as expected but issue is unable to configure "maxAttempts/openTimeout/resetTimeout" as env variables (error is should be constants). My question is how use resilience4j to achieve the below requirement?
also please suggest there is a way to pass env variables to "maxAttempts/openTimeout/resetTimeout".
#CircuitBreaker(value = {
MongoServerException.class,
MongoSocketException.class,
MongoTimeoutException.class
MongoSocketOpenException.class},
maxAttempts = 2,
openTimeout = 20000L ,
resetTimeout = 30000L)
public void insertDocument(ConsumerRecord<Long, GenericRecord> consumerRecord){
retryTemplate.execute(args0 -> {
LOGGER.info(String.format("Inserting record with key -----> %s", consumerRecord.key().toString()));
BasicDBObject dbObject = BasicDBObject.parse(consumerRecord.value().toString());
dbObject.put("_id", consumerRecord.key());
mongoCollection.replaceOne(<<BasicDBObject with id>>, getReplaceOptions());
return null;
});
}
#Recover
public void recover(RuntimeException t) {
LOGGER.info(" Recovering from Circuit Breaker ");
}

Answer 1

You are not using resilience4j, but spring-retry.
You should adapt the title of your question.

Answer 2

CircuitBreakerConfig circuitBreakerConfig = CircuitBreakerConfig.custom()
.waitDurationInOpenState(Duration.ofMillis(20000))
.build();
CircuitBreakerRegistry circuitBreakerRegistry = CircuitBreakerRegistry.of(circuitBreakerConfig);
CircuitBreaker circuitBreaker = circuitBreakerRegistry.circuitBreaker("mongoDB");
RetryConfig retryConfig = RetryConfig.custom().maxAttempts(3)
.retryExceptions(MongoServerException.class,
MongoSocketException.class,
MongoTimeoutException.class
MongoSocketOpenException.class)
.ignoreExceptions(CircuitBreakerOpenException.class).build();
Retry retry = Retry.of("helloBackend", retryConfig);
Runnable decoratedRunnable = Decorators.ofRunnable(() -> insertDocument(ConsumerRecord<Long, GenericRecord> consumerRecord))
.withCircuitBreaker(circuitBreaker)
.withRetry(retry)
.decorate();
String result = Try.runRunnable(decoratedRunnable )
.recover(exception -> ...).get();
